'Sandals' in the Bible

None [is] weary, and none among him stumbles; none slumbers and none sleeps. And no loincloth on his waist is opened, and no thong of his sandals is drawn away.

at that time, Yahweh had spoken by the hand of Isaiah son of Amoz, saying, "Go and loosen the sackcloth from your loins, and take off your sandals from your feet," and he had done so, walking naked and barefoot.
